So, a whole day has been spend trying to install docker. This is the error i keep getting. I used the official approach from docker, and also tried the digital ocean installation guide.

Setting up docker-ce (18.04.0~ce~3-0~ubuntu) ...
Job for docker.service failed because the control process exited with error code.
See "systemctl status docker.service" and "journalctl -xe" for details.

After restarting and journaling the error:
I got this ->

I also download a debian package and installed, it also failed.

I was able to install it using this page steps: https://gist.github.com/levsthings/0a49bfe20b25eeadd61ff0e204f50088

sudo apt-get update
sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo apt-key fingerprint 0EBFCD88

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu zesty stable"

sudo apt-get update
sudo apt-get install docker-ce

Can you check if the docker -ce was installed and service is running .. sometimes if you try multiple installations,, it may throw this type of error.
If so, uninstall and try to install following steps from this tutorial -

Essentially you will run following commands -

1. 
   

   install the dependencies first

   
   
   

    sudo apt install apt-transport-https ca-certificates curl software-properties-common
   

   
   


2. 
   

   add the GPG key for the official Docker repository to the system:

   
   
   

   curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
   

   
   


3. 
   

   Add the Docker repository in sources.list.d to APT sources using below command

   
   
   

   sudo add-apt-repository "deb [arch=amd64] 
   https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable edge"
   

   
   


4. 
   

   verify if you are able to install Docker from Docker repository

   
   
   

   apt-cache policy docker-ce
   

   
   


5. 
   

   Finally, install Docker CE package with below command

   
   
   

   sudo apt-get install -y docker-ce
   

   
   

Voila, you have installed Docker-CE. you can verify installation by checking the version of docker-ce installed

docker --version
